We did not meet with Wimonpak. This is an apartment in a hotel. I'm not going to cross-check it, the listing description might be accurate.

Pro:
It is clean.
The wooden materials are great. (insects love them, too)
The Saphan Taksin port/BTS (skyline~metro) is 10 minutes away.

Contra:
The girl, who let us in, don't speak english, not a word.
We had to buy toilet paper.
The knife we got was sticked with a scotch-tape.
Something had bitten us there, but I don't know what.
You can't open the windows, there is a bad odor in the neighborhood. (The listing should mention this.)
Anyone could crawl in, it is in the first floor with a fence under the balcony. (The listing should mention this, also. It is not a coincidence, why everyone has bars in front of their windows...)

Note:
The apartment is in Bangkok, the neighborhood is like you can imagine, take a look it on Google Maps.

I suppose this is the high quality in Bangkok.
